In this paper, the authors tried to establish the association of alcoholism with arterial hypertension as well as with risk factors for atherosclerosis, which are invariably accompanying arterial hypertension, in engine-room personnel (N = 80), in other seamen of the "Jugolinija" (N = 119), and in the control group which was made up of employees of the Technical Department, Shipyard, "3. maj", Rijeka (N = 108). The chi 2-test showed a statistically significant difference in the prevalence of alcoholism, and the t-test a statistically significant difference in the daily consumption of alcohol between the two groups of seamen and the control group. The prevalence of alcoholism and the daily consumption of alcohol were higher in seamen. There were no such differences between the two groups of seamen. Similarly, arterial hypertension was more prevalent and systolic (SBP) and diastolic blood pressure (DBP) were higher in the two groups of seamen compared with the control group. Since, there were no significant linear correlations between the alcohol consumption and SBP and DBP, it could not be said that higher values of SBP and DBP were positively related to the greater consumption of alcohol in seamen as compared to the control group. No significant linear correlation was found between alcohol consumption and studied risk factors too. However, higher prevalence of arterial hypertension in alcoholics among the engine-room personnel suggested some association of the alcohol consumption with arterial hypertension.

Reduction of arterial compliance leads to a higher systolic (SBP) and a lower diastolic blood pressure (DBP). The increasing occurrence of reduced arterial compliance is responsible for the steep increase in SBP after the age of 50 years and also for the constancy and later decline in DBP. Reduced arterial compliance will blur the relationship between mean arterial pressure and DBP. This may change the relationships between cardiovascular events and DBP. The possibility of non-causal co-existence of reduced compliance and atherosclerosis is discussed. Such a co-existence would markedly influence the relationship between cardiovascular events and DBP. Finally, the influence that reduced compliance might have on the shape of the relation between cardiovascular episodes and diastolic and systolic blood pressure is discussed.

The effects of the beta-blocker tertatolol on plasma lipids and lipoproteins were studied in two groups of 10 normolipidemic (group I) and 10 hyperlipidemic (group II) hypertensive patients, for a period of 3 months. The efficacy of tertatolol was confirmed by a reduction in heart rate (HR), and in systolic (SBP) and diastolic (DBP) blood pressure, in the supine position and after 1 min in the upright position. Triglyceride (TG) levels were increased by treatment in both groups (+20% and +22%, respectively; p less than 0.05), as were VLDL levels (+16% and +24%, respectively) although the rise in the latter was not significant. There were no significant differences in levels of HDL cholesterol (HDL-C), HDL, or apoproteins A and A1 (APO A, APO A1). Total cholesterol (TC) levels were increased by treatment in group I (+10%; p = 0.050) and decreased in group II (-9%, not significant), LDL-C being the principal fraction involved in these changes. There were no significant differences in levels of APO B. The ratio between TC and HDL-C levels remained unchanged. Given the current state of our knowledge concerning lipid markers for atherosclerosis, these results indicate that chronic administration of tertatolol may be considered devoid of 'atherogenic' effects.

The associations of life-style variables, namely type of dietary fat, alcohol use, smoking, obesity, physical activity and oral contraceptive use with serum lipids, insulin and blood pressure were studied in 1398 adolescents and young adults aged 15-24 years. Smokers were more often physically inactive and regular users of alcohol compared to non-smokers. In females, smoking and alcohol use were more prevalent among oral contraceptive users. Independent effects of life-style variables on lipids, blood pressure and insulin were assessed with multiple linear regression models. In both sexes, body mass index was positively related to low density lipoprotein cholesterol (LDL-C), triglycerides (TG), systolic (SBP) and diastolic (DBP) blood pressure and insulin, and negatively with high density lipoprotein cholesterol (HDL-C). Leisure time physical activity was associated with lower levels of insulin among males. Smoking was related with 0.07 mmol/l lower HDL-C levels and about 0.09 mmol/l higher TG levels in males. In both sexes, smoking was related with lower levels of SBP. In males, alcohol use was associated with 0.05 mmol/l higher level of HDL-C (P = 0.06). In females, alcohol use was associated with lower levels of LDL-C and TG. Oral contraceptive use was associated with approximately 0.15 mmol/l higher levels of TG and about 4.0 mmHg higher SBP. Preferring butter over margarine as dietary fat was associated with 0.26 and 0.19 mmol/l higher levels of LDL-C in males and females, respectively. Accumulation of adverse life-habits contributed to the clustering of an atherogenic lipid profile and high blood pressure. In males, those with 4 selected life-habits present, namely obesity, smoking, inactivity and the use of butter, had 5.5 times greater risk (95% confidence interval 1.4-20.7) of belonging to the group with high LDL-C, low HDL-C and high DBP compared to those with zero or one life-habits present. These data demonstrate that life-habits show clustering in adolescents and young adults. Individuals with many adverse life-style risk factors present are at increased risk of having an atherogenic lipid and blood pressure profile.

Hypertension is associated with an increased risk of atherosclerosis. Free radical oxidative damage has been implicated in the atherogenic process. We measured levels of the antioxidants uric acid, thiols, vitamins C, A and E as well as the total antioxidant capacity in 21 normotensive controls, 22 patients whose hypertension was controlled on drugs and 30 patients with uncontrolled hypertension. Mean BPs in the groups were 125/76, 132/80 and 181/98 mmHg, respectively. When compared with controls, both hypertensive groups had significantly lower serum ascorbic acid (54 +/- 5 vs. 37 +/- 6 vs. 38 +/- 5 mumol/l, P < 0.05) and albumin-corrected thiol levels (9.91 +/- 0.18 vs. 8.69 +/- 0.20 vs. 8.92 +/- 0.19 mumol/g, P < 0.05). The levels of the other antioxidants did not differ significantly between the groups. Levels of von Willebrand factor, a marker of endothelial damage, were correlated with SBP but not with antioxidant status. We conclude that hypertensive subjects have lower levels of the antioxidants vitamin C and thiols and this may reflect greater oxidative consumption. The implications for atherogenesis and endothelial function and integrity in hypertension are discussed.

Interest in research on atherosclerosis involving children has been the consequence of confluent evidence that atherogenic process begins in early life and grows silently until the occurrence of clinical events in middle-age or later. We carried out a cross-study in the Mediterranean area on a random sample of a secondary school of Casteldaccia (a farming and fishing village located on the Northern coast of Sicily, East of Palermo), consisting of 186 teen-agers (103 males and 83 females) aged between 10 and 13 years (average age: 11.3 +/- 0.2 years). We determined: total cholesterol, triglycerides, HDL-cholesterol, LDL-Cholesterol, apolipoproteins A1 and B, glycaemia, body mass index (BMI), systolic and diastolic blood pressure. Dietary habits were recorded on two occasions by a weekly diary (of the 7 days food record type) with the collaboration of dieticians. The prevalence of plasma cholesterol levels between 170-200 mg% and exceeding 200 mg% was 24.2% and 12.4% respectively, of overweight (BMI > 25) was 9.7% and of hypertension (SBP > 125 and/or DBP > 85 mmHg) was 8.6%. In comparison with Mediterranean diet according to Euratom study (1969), the following are the most impressive findings: an increase of cholesterol (+54%) and fat intake (+2% of total calories), a reduction of fibre intake (-32%) and an increase of 2S-P difference (+27%) and of total fats/fibre ratio (+53%).

Atherosclerosis in diabetic subjects is improved by the reduced repair capacity of endothelial damage and by the increased platelet aggregation, peculiar to diabetic pathology. The contemporary presence of high blood pressure, diabetes and lipoidoproteinosis, increasing the possibility of cardiovascular damage, also under well-controlled blood pressure values, certainly increases the risk of atherosclerosis. However we have valued the presence of lipoidoproteinosis in 52 of our diabetic-hypertensive patients in a follow-up of 40 months. The patients have been split in to two groups of 26 patients each, one being treated with nifedipine, the other to with captopril. The data obtained have been compared with the data for the two control groups (non diabetic patients). The selection has been carried out according to established criteria. We have investigated: glycaemia, total cholesterol, HDL-C, LDL-C, triglycerides, tot. Chol./HDL-C, LDL-C/HDL-C. During follow-up the blood pressure values were significantly reduced (p < 0.01) (captopril: delta SBP = -13.88, delta DBP = -12.38, nifedipine: delta SBP = -22.03, delta DBP = -21.35). In the nifedipine group lipoidoproteinosis has been more marked: delta% glicaemia = +17.69, delta% cholesterolemia = +20.11; delta% CFR = +18.57; LDL-C = +35.11; delta% VRF = +34.61, while in the patients treated with captopril we have had the following results: delta% glycaemia = +15.43; delta% cholesterolemia = +16.36; delta% LDL-C = +26.68. The control group with nifedipine treatment have shown only increased values of cholesterolemia: delta% = +4.80, moreover in the control group treated with captopril we have observed a reduction of VRF: delta% = -15. A significant relationship between total cholesterolemia and glycaemia in the group with nifedipine treatment (p < 0.01) and captopril (p < 0.01) has been reported. This study could appear to underline the autonomic nervous system activation by nifedipine which does not affect lipoidoproteinosis in diabetic hypertensive subjects. This would seem to confirm on the contrary, the utility of captopril in the treatment of atherosclerotic subjects, as diabetic hypertensive patients.

Genetic influences in cerebrovascular disease (CVD) may act either independently or by predisposing to, or modulating, the effect of risk factors such as hypertension. Factors involved in the pathogenesis of atherosclerosis, thrombosis and vasoconstriction are important in CVD. The angiotensinogen gene has recently been linked with essential hypertension in affected sibships and a particular polymorphism in exon 2 of the angiotensinogen gene, a threonine to methionine substitution at position 235 (M235T), has been associated with pre-eclampsia and hypertension. In this study we examined the relation of M235T polymorphism to cerebrovascular disease and carotid atheroma in 100 consecutive Caucasian patients with internal carotid artery territory ischaemia (TIA or stroke), presenting to a carotid ultrasound service. Forty five age-matched controls (mostly patients' spouses) were also studied. Hypertension was defined as current treatment with anti-hypertensive agents, or SBP > 160 mm Hg or DBP > 95 mm Hg. Twelve of 100 cases (12%) and eight of 45 controls (12%) were homozygous for the T235 allele. T:M allele ratios were 0.34:0.66 in cases and 0.34:0.66 in controls. There was no relation between the polymorphism and either internal carotid stenosis or common carotid artery intima-media thickness. In the cases, mean percentage internal carotid artery stenosis was TT 18.3 (SD 18.7)%, MT 38.0 (27.1)% and MM 36.8 (30.2)%. Mean intima-media thickness was TT 0.87 (0.18) mm, MT 0.95 (0.34) mm and MM 0.88 (0.23) mm. There was no relation between the polymorphism and hypertension (TT 11 of 100 cases, six of 45 controls).(ABSTRACT TRUNCATED AT 250 WORDS)

The thoracic aorta is frequently involved in atherosclerotic lesions associated with familial hypercholesterolemia (FH). Transesophageal echocardiography (TEE) allows quantitative evaluation of the wall properties of the thoracic aorta. Using TEE, we tested whether atherosclerosis of the thoracic aorta in FH could be improved by cholesterol-lowering therapies. The subjects investigated were 22 FH patients and 22 age-matched normal subjects. The descending aorta (DA) was divided into four longitudinal portions of equal length. Atheromatous lesions of each portion of the DA were scored by character and extension of lesions by biplane two-dimensional TEE. The scores of atheromatous lesions from all four portions of the DA were added together to give the total atheromatous score (TAS). We also measured instantaneous dimensional changes of the DA in a cardiac cycle by M-mode TEE and blood pressure by a cuff method and calculated the stiffness parameter beta (In[SBP/DBP]/[Dmax-Dmin]/Dmin), where SBP is the systolic arterial blood pressure, DBP is the diastolic arterial blood pressure, Dmax is the maximum aortic dimension during the ejection period, and Dmin is the minimum aortic dimension during the preejection period. TAS was higher in FH (3.70 +/- 1.32) than normal (0.62 +/- 0.54, P < .0001) subjects. Beta in FH (10.35 +/- 4.87) was greater than in normal (5.10 +/- 1.25, P < .0001) subjects, but there were no significant differences of DA dimensions between the groups. In both normal subjects and FH patients, beta correlated with age (r = .52, P < .02 and r = .59, P < .005, respectively). In FH patients, beta and TAS correlated well with pretreatment total cholesterol levels (r = .43, P < .05 and r = .60, P < .005, respectively). In 12 of 22 FH patients, strict cholesterol-lowering therapies with diet and cholesterol-lowering drugs (pravastatin and probucol) were undertaken for 13 months. Cholesterol levels were significantly decreased from 333 +/- 45 to 219 +/- 39 mg/dL (P < .0001); this was associated with significant decreases in beta and TAS (from 9.88 +/- 5.03 to 7.88 +/- 3.92, P < .005, and from 3.61 +/- 1.50 to 2.94 +/- 1.22, P < .0005, respectively). In FH patients, the incidence and severity of morphological and physiological atherosclerosis of the DA were significantly higher than in age-matched normal subjects. A significant regression of atherosclerosis was achieved by strict cholesterol-lowering therapies in relatively young FH patients.

The epidemiology of a common measure of cardiovascular reactivity, the change in systolic blood pressure (DeltaSBP) from the supine to the standing position, is described in a cohort of 13 340 men and women aged 45 to 65 years enrolled in the Atherosclerosis Risk in Communities (ARIC) Study. The distribution of DeltaSBP was found to be symmetrical and unimodal, with a mean value near zero (-0.45 mm Hg). The range of DeltaSBP was from -63.2 to 54.3 mm Hg, and the standard deviation was 10.8. Stratification of DeltaSBP by race and gender shows a slight shift in distribution toward higher values for black men and women. DeltaSBP was categorized into deciles. Participants in the top 30% and bottom 30% of the distribution were compared with individuals in the middle 40% of the distribution, who had little or no change in SBP on standing. Participants in the bottom 30% (ie, SBP decreased on standing) were significantly older, had a greater prevalence of hypertension and peripheral vascular disease, had higher values of SBP, and had more cigarette-years of smoking. Among participants in the top 30% (ie, SBP increased on standing), a significantly larger proportion were black, mean seated SBP was higher, and the predicted risk of developing coronary heart disease after 8 years was greater. The response of SBP to change in posture showed considerable variability in a population sample of middle-aged adults. Cardiovascular morbidity, sociodemographic factors, and cigarette smoking were associated with the magnitude and direction of the postural change.
